This release fixes a crash when running extensions like the Subscribe in Feed Reader sample. It also fixes a problem in Google Calendar where overlapping calendar items were invisible because they were being displayed with 0 width. This update is being released for Windows, Mac and Linux.

[r29284] *Breaking Change* Only one browser action or one page actions is now allowed per-extension. We are experimenting with the idea of a direct correspondence between extensions and visible UI features. We think this may improve managability. (Issue: 24473)

Mac: If an older version of Chrome is running when this version is automatically installed the running version will not quit cleanly and will spike the CPU at 100%. It will be necessary to Force Quit the application. Use Cmd-Option-Escape to open the Force Quit dialog.

Mac: Cmd-opt-left/right navigate history instead of switching tabs (Issue:25396). Use cmd-{/} as workaround.

This week's dev channel update includes a number of fixes. It introduces the Native Client as a built-in feature for the first time on Windows. Some additional Extensions APIs also make their first appearance.
